2007 Chrysler Pacifica Touring 4.0L V6, 43K miles. Thrown the Manifold Tuning Valve position senseor code (P2078) three times in the last month.
I've have some degree of understanding what an MTV does. But I don't know enough to grasp what could be wrong with it.
Probable causes on the scanner readout are:
-Linkage stuck or broken.
-Mechanical condition.
-Intake Manifold Tuning Valve.
Is it similar enough to a throttle body that it has perhaps gotten gummed up and needs cleaning? Or is it more like a Throttle Position Sensor with a plunger that might need replacing?
There is very little info. on MTVs out there. Parts store websites don't even list MTVs. Repair manual mentions them but says little else.
Any guidance would be great. As always, knowledge is power. Thanks.
